An analysis of PAX1 in the development of vertebral malformations. Due to the sporadic occurrence of congenital vertebral malformations, traditional linkage approaches to identify genes associated with human vertebral development are not possible. We therefore identified PAX1 as a candidate gene in vertebral malformations and congenital scoliosis due to its mutation in the undulated mouse. We performed DNA sequence analysis of the PAX1 gene in a series of 48 patients with congenital vertebral malformations, collectively spanning the entire vertebral column length. DNA sequence coding variants were identified in the heterozygous state in exon 4 in two male patients with thoracic vertebral malformations. One patient had T9 hypoplasia, T12 hemivertebrae and absent T10 pedicle, incomplete fusion of T7 posterior elements, ventricular septal defect, and polydactyly. This patient had a CCC (Pro)-->CTC (Leu) change at amino acid 410. This variant was not observed in 180 chromosomes tested in the National Institute of Environmental Health Sciences (NIEHS) single nucleotide polymorphism (SNP) database and occurred at a frequency of 0.3% in a diversity panel of 1066 human samples. The second patient had a T11 wedge vertebra and a missense mutation at amino acid 413 corresponding to CCA (Pro)-->CTA (Leu). This particular variant has been reported to occur in one of 164 chromosomes in the NIEHS SNP database and was found to occur with a similar frequency of 0.8% in a diversity panel of 1066 human samples. Although each patient's mother was clinically asymptomatic and heterozygous for the respective variant allele, the possibility that these sequence variants have clinical significance is not excluded.

Pax genes encode an evolutionary conserved group of transcription factors with multiple roles during embryonic development and for cell type specification in normal and malignant tissues of the adult organism. In mice, Pax1 is required for the formation of specific skeletal structures as well as for the development of a fully functional thymus. In humans, the PAX1 locus has been linked to otofaciocervical syndrome, idiopathic scoliosis, and to a higher susceptibility for androgenic alopecia. In addition, the methylation status of PAX1 has recently emerged as a sensitive marker for predictive screening of cervical cancer. To provide a reagent for reproducible detection of Pax1 expression, we have generated rat monoclonal antibodies (MAbs) against the murine Pax1 protein. MAbs of one clone (clone 5A2) specifically detect mouse Pax1 protein in Western blot analyses. Moreover, the anti-Pax1 MAbs cross-react with human PAX1 protein and are applicable in immunohistochemical detection procedures using paraformaldehyde/formalin-fixed tissues embedded in paraffin. The anti-Pax1 MAbs provide a reliable reagent for reproducible Pax1/PAX1 protein expression analyses and, therefore, may help to improve diagnostic protocols in clinical settings involving deregulated expression of Pax1/PAX1.
